Impulse Testing of Power Transformers For Effective Resistors Using Orcad Pspice Authors

High voltage equipments are often placed in open air and they are often exposed to lightning strike as well as surge voltage. Most of such high voltage power equipments are placed in the power transmission line. They are sustaining high surge voltage during the lightning phenomena. To protect all such power equipments and quality power supply the study of lightning characteristics is most important for every power engineers. The main objective of this paper is to simulate the standard impulse waveform of the impulse voltage generator circuit at front & tail resistive load and obtained results are showing graphically. The whole systems are studied in the Pspice software. Keywords:-Impulse generator, power transformer, Pspice, spark gap. 1
